BQTTLE-STOPPERH Specification of Letters Patent. Application filed-April30, 1906. Serial No; 314,426.

To all whom it may concern.-

Be it known that I, WILLIAM H. Down, a citizen of the United States,residing at the city of New York, in the borough of Brooklyn and Stateof New York, have invented certain new and useful Improvements inBottle- Stoppers, of which the following" is a full, clear, and exactdescription.

My invention relates to bottle, caps or stoppers," particularly to thatclass in which the cap is normally held to the bottle by cam or othermeans and is removable or replaceable whenever desired.

The tion is to facilitate the assembling of the various parts when thecap is manufactured.

Withthis and other objects in view'the invention consists in the formand arrangement of the cam-slot, as hereinafter set forth and shown, andfinally. particularlypointed out in the appended claims.

in the drawings, Figure 1 is a side view of the bottle-cap embody ng theprinciples of my invention. Fig. 2 is a similar view showing the cam inposition to be assembled upon the other parts. Fig. 3 is a detailsectional view of the clamping-handle, showing its re-' lation to theWire clamping-ring when being assembled thereu on.

in assembling t e parts of the Kirkegaard stopper hitherto used, andparticularly the form in which the cam-slot has both of its walls curvedand constitutin the ca1n-surfaces, a great deal of difficultylias beenfound in placing the cam upon the wire ring. For the urpose ofassembling the parts more uic y, with greater facility and more 0 eaply,l have devised a construction in which the cam is capable of performingall of the functions that it had hitherto and at the same time may beassembled upon the wire ring by a simple movement, so that the troubleand ex ones of this part of themesess is almost wholly eliminated.

The improvement consists, broadly stated, in enlarging the lower end ofthe cam-slot to such a size that it will receive one of the hooks at theend of the wire rin by a simple sidewise movement and without anydifficult manipulation.

' bottle-cap aving depending fingers 2 and a wire ring 3, the ends 4; ofwhich are bent around to form hooks. 5 denotes the cam,

principal object ofthe present inven-- having acurved slot 6 and ahandle :7 i The cam is perforated at 8 to fit upon one ofthe hooks 4.

-. Patented Sept. 1-8, 1906..

Instead of making the lower end of the v curved slot 6 terminateabruptly, as in the usual form, I continue the slot to a point beyondits normal working portion and form an enlar ement at the termlnal end,as shown at 9. he enlargement is preferably elongated in a directionpassing through the pivot-point 8. The amount of such elongationcorrespondsto the amount that the hooks 4: are bent around or turnedover.

The use and operation of'the invention are as follows:

The ca s are formed with the wire rings assemble therein by aspecialmachine, and the camsare likewise produced in quantities with the slot 6unched out therein to the proper shape. t is then merely necessary toassemble the cam 5 with its perforation 8 uponone of the hooks 4, therelation at this time being clearly shown in Fig. '3. In this processthe cam is held so far tilted up that the elongated hole 9 comesopposite the other hook '4. In this relation the direction of elongationof the hole 9 corresponds to the length of the hook 4:, so that the camslips over the hook by a simple sidewise movement. The handle 7 is thendepressed, which causes the cam-slot '6 to move downward on its hook4until the ring and fingers '2 arrive at their normal or untensionedstate. This condition corresponds to a middle position of the cam-slot 6upon its hook, so that there is no liability of the hook to ever reenterthe elongated hole or extremity 9 of the slot. The corners 10 of theslot at the point of its junction with the elongated hole 9 are,however, rounded, so as not to impede the rentrance of the hook into theslot in any case should the hook be accident ally displaced into theelongated hole.

Whenever the cap is used, it is laced on a bottle and the cam-lever 7pushe downward uniform widt a cam havin a curved slot of substantiallyI] throu hout its middle portion to engage one of said hooks, and havingan enlar ement at the end of said slot to facilitate 5m assembling ofthe cam upon the ring. 2. In a bottle-cap havin depending fingers and aclamping-ring wit hooks thereon,- a cam he a curved slot ofsubstantially uniform throughout its middle portion and a perforationrespectively adapted to receive said hooks, the extremity of said slotbejin enlarged to form an elongated hole, as

and or the p ose set forth.

3. In a bott e-oap ha depending fingets and a olampingqing wit hooksthereon, a earn having a'eurved slot and a perforation adapted toreceive said hooks, said curved slotbein formed to receive its hook atabout the mid le portion of the slot when the ring and fin ers are intheir untensioned state, and sai slet having an enlargement at its lowerextremity to form a hole, the width of which corresponds to the lengthof said hooks. 4. In a bottle-cap depending fi11 gers and aclamping-ring wit hooks thereon, a cam having a curved slot and aperforation respectively adapted to receive said hooks, said'slot bein',formed to receive its hook at about its mid e portion in the normal orun tensioned state of said ring and fingers, and said slot being formedat its lower extremit with an elongated enlargement having roun edcorners at its g'unction with said slot, the

= elongation or sai enlargement lying in a direetiontoward saidperforation, as and for the purpose set forth.

In witness whereof I subscribe my signature in the presence of twowitnesses.
